One afternoon I was feeling thirsty and decided to make myself a pot of tea. I grabbed my tea kettle and dumped out all the water that was sitting in there and replaced it with fresh cool water. I placed the full kettle on the stove and turned on the burner to the highest setting to boil the water. While the kettle was warming I took out my teas and tea pot. I decided to have green tea that day, and scooped about 5 teaspoons of tea into the pot. Once the kettle was steaming, I turned off the stove and let it cool down a little. I poured the water in the pot and replaced the lid of the pot. When the tea was done steeping, I poured myself a cup into a tea cup that I had warmed up with some of the excess hot water. I poured in some sugar with a spoon and gave it a stir. Then I enjoyed my tea when it was cool enough to drink.
How many different types of teas did they drink?
